It’s a trio of Torn, Berne, and drummer Ches Smith. That’s 50% of Torn’s band, Prezens, plus 50% of Berne’s band, Snakeoil.
As Torn explains in Westword Music, it’s like Prezens without the keyboard, with the guitar as the lone chordal instrument (to the extent that you can discern chords in the sound).
The result is a lot like Prezens. Torn blasts his new-age-gone-evil guitar sounds: aluminum soundwalls and squeals, sci-fi sonic blasts. Berne careens and screeches in a way that blends into the mix — although he does take a jazzy turn occasionally; see around the 15:00 mark in the video below, after which they even get into a near-Calypso groove. Smith’s drumming is the element that keeps the whole assembly tied to earth, grounding it in aggressive fills and improvising.
Not-quite-related: I’ve been remiss in not mentioning the massive Tim Berne Q&A published by The Village Voice. It’s part of a series of Q&As that’s been fantastic; I especially liked the Ches Smith edition.
